Keratin-20 is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. KRT20 plays a significant role in maintaining keratin filament organization in intestinal epithelia. When phosphorylated, it plays a role in the secretion of mucin in the small intestine. Diseases associated with KRT20 include Merkel cell carcinoma and ovarian Brenner tumor. Among its related pathways are cytoskeletal signaling and developmental biology.

Reconstitute the lyophilized antibody with deionized water (or equivalent) to a final concentration of 0.5 mg/ml.

Specificity

The product is specific for human KRT20. This antibody binds with recombinant KRT20 protein in ELISA and western blot.

Storage
